How many processors and how much memory does it take to simulate a human brain? Isn't it a good idea to simulate a human brain and store all the knowledge in it and let it gain experience with time? This artificial human brain can live forever and gain experience.

bye!

We don't yet fully understand how the human brain works, much less how we could go about building an artificial one.

you can't simulate thoughts or feelings through a machine

impossible

Is it really? What are thoughts and feelings really? Electric signals that start off somewhere as positive and negative charges controlled through chemicals.

Its funny because what we can't imagine as something that can be created has humble beginnings itself.

So is it really that impossible given the right computing power and the right mind to create such algorhthims?

I see such a process starting at the most basic level. Like a program that sends electric charges (ofcourse they are just 1 and 0s in code) and from there a chain reaction starts to test to see if that program could evove to act like a primitive brain.

We dont need to produce the electrical signals as they are. We can have a model in which we can simulate electrical signals. It has to have so much storage to accommodate all the neurons, though.

good point

I,Kmguru,Chris and others have written some interesting article that might help you.
thanks!

A neural network is the best way I know of to simulate a human brain. The problem is, the human brain has so many network connections and layers. A simple nn is simple enough to make, but massive amounts of memory (no idea how much) would be required to make something equivilent to the human brain. Then you have to figure out how to give it input. Do you give your little program the ability to send messages across the internet? Should you teach it HTTP so that it can browse (if that's possible). Or maybe put it into a robot body? Personally I'd be scared to hook up something like that to the internet and let it go hog wild.

Fortunately anything like that is way way way off into the future if it's even possible.

it is very possible to do such things, and is happening as we speak and quite fast Blackstream. The "Cog" project is currently underway. this robot will be the most intelligent AI, it will be able to think, hear, feel, touch, learn and speak

Link or source please for this "Cog" project. AIs can already think, hear, feel, touch, learn, and speak, however they do it in a very limited way as compared to humans. I could write a primitive chess program for example than can think and learn. Add in a mic so that it can hear, some weight sensors so that it can feel, and some speakers so that it can speak, and I'm set. But it's nowhere near human level and can't think on the level that a human can.

Computer memory is not the problem, and complexity is not an issue (well not much). Time is the big issue. The brain is a massive parallel processing machine. Chemical and quantum forces drive the processing speed.

Imagine simulating every particle down to the quantum level..

Even if we get all the physics right, can the computation occur in our life times???

Well Time and the fact that we don't know any good algorithms to create an actually true to life AI. I took a very good ai course and found out just how hard it is to do even the "simplest" things.

Once we find the unified theory we find AI.. Its then a question of processing power.

If we find the whatever the unified theory you say is. Scientists and AI programmers claimed like 20, 30 years ago, we'd have near life-like ais by now. We have hardly progressed in that direction. Sure we can make super-specialized ais in something like chess, really really good. But not a just general intellegence. We've made little progress in that field.

Have any of you looked into Quantum Computation? go to www.qubit.org and check it out. They say it is possible to simulate any physical reality, and using quantum computation the difficulty of an algorithm is not a multiple as with classic computation but a square root, that means signifigantly less memory is needed to process even the hardest equasions, in fact time is not even a factor, provided it has enough memory all algorithms would take alot less time to process. this all means simulating the human mind wouldnt be IMPOSSIBLE, but given current technology, inacheiveable. (ps AI and simulating the processes a mind goes through are completely different, and shouldnt get mixed up.)

the humen brain is estimated to have 10-1000 teraflops of processing power

To emulate human thought though will require a neural network or Field Reprogamable Gate Array design and possible analog processing.
